Face Fat Auto is an F1 variety that was created by breeding the two auto-flowering varieties known as GMO Auto and Fatso Auto. Mature buds are shiny with resin and are also extremely potent. These buds tend to display some purple colouration. Atlas Seed claims between 99.9% - 99.96% female plants from these auto-flowering seeds.

Face Fat Auto has plenty of hybrid vigour and develops into a plant with good side-branching. These plants also have a good tolerance to both the cold and drought. Well-spaced internodes allows enough room for the flowers to develop fully growing into dense buds. The complete grow-cycle takes approximately 75 days from germination through to harvest.

Face Fat Auto has a powerful smell of fuel. THC content is very high reaching as much as 28%.
